The best time to buy olive oil is during or after the most recent harvest, when the oil is freshest, closest to the date it was pressed.
For Northern Hemisphere oils, from Mediterranean countries including Spain, Italy, Greece, Tunisia, and Portugal, the new crop reaches the market from about November until spring. For Southern Hemisphere oils from countries like Chile, Argentina, and Australia, the fresh window falls around midyear.
Look for a recent harvest date, which promises more flavour, higher polyphenol content, and the longest shelf life in the bottle.
The amount of olive oil available depends largely on the size of the most recent olive crop. Once a major upcoming harvest is confirmed and supply is plentiful, prices tend to be lower, though many factors affect olive oil prices.
Why timing matters with olive oil
From the moment the oil is mechanically pressed from olives, the clock starts: the polyphenols, the healthy antioxidants, begin to decline, the aromas soften, and oxidation gradually begins. It is at its best when freshly produced, so the goal when buying is to get as close to the harvest as possible.
When is olive oil harvested?
Olives grow on both sides of the equator, and oil is produced at two different times of year. Knowing the calendar tells you when each origin's new crop will actually be available.
In the Northern Hemisphere (Spain, Italy, Greece, Tunisia, Portugal, Turkey, and California, U.S.), harvest usually takes place from October to February, so the new oil is on the market during that time and afterwards, well into the spring, depending on how much oil is produced in the season and how much is sold.
In the Southern Hemisphere (Chile, Argentina, Australia, and South Africa), the harvest usually runs from March to July, though timing varies by country. Argentina tends to start earlier, around February, while Chile tends to start later, around April/June. The oil is available mid-year.
The benefit of having production in two hemispheres is that fresh oil is available year-round. However, Mediterranean production dominates this market, and the majority of the world’s olive oil comes from there. Mediterranean producers delicately balance selling their oil at good prices and maintaining healthy stock levels until the next harvest, so as not to run out of oil.
Within each season, the timing of the harvest affects the oil itself. Early-harvest oils, picked while the fruit is still green, are bolder, more bitter and peppery, and richer in polyphenols, though they usually yield less oil per olive. Late-harvest oils, from riper, darker fruit, are milder and smoother, give a higher yield, and normally carry fewer antioxidants.
Best time to buy for freshness
Olive oil with the strongest flavour and maximum nutritional value is that purchased as close to the most recent harvest as possible and used within a reasonable time.
● 0–6 months: peak condition with maximum polyphenols, full aroma, and lowest acidity.
● 6–12 months: still very good if stored properly, though the peppery notes may soften.
● 12–18 months: acceptable for cooking, with noticeably reduced character and nutritional value.
● 18 months and beyond: may be flat or even rancid.
Once a bottle of olive oil is opened, oxidation accelerates, so it is best to consume it within a couple of months. It is important to buy a reasonable amount based on how much is needed.
Best time to buy for price
It is impossible to predict olive oil prices, as the market is highly volatile and prices vary with many factors. The main price driver is supply, not the production calendar.
Olive oil prices usually rise and fall with the size of the olive harvest, and harvests vary greatly from year to year depending on the weather in a given region and the olive tree's alternate-bearing rhythm of a heavy crop one year followed by a lighter one the next. This is why it cannot be assumed that prices will automatically be lowest after harvest.
In a low-yielding crop year, prices may climb even as the new oil arrives. This occurred during the 2023/24 campaign, when drought across Spain, the world’s largest producer, drastically reduced production and pushed prices to record highs. In a high-yielding crop year, an ample supply may soften prices once the harvest size is clear.
If price is your priority, price clarity arrives with the harvest. From October to December, olive oil mills report their first volumes, and the market learns how big the Northern Hemisphere crop really is. This is when prices adjust themselves relative to how much oil is being produced and will be available. It is when market participants are most attentive to price movements, and very important for planning purchases.
Right now, olive oil prices are low compared with the 2024 spike and its aftermath. The following seasons performed much better, and a strong 2026/27 Spanish crop is widely expected. For buyers, that points to continued competitive pricing and favourable conditions for purchasing or locking in supply.
Best time to buy olive oil in bulk
For businesses, including foodservice, manufacturers, packers, and retailers, the timing is the same, but the stakes are higher.
The window around the new crop, from late autumn into winter for Mediterranean oil, is when fresh bulk volume is most available. In a confirmed large-crop year, this is the time to contract volume at competitive rates. Buyers lock in quality-certified bulk volumes, securing both price and supply that meet chemical and sensory standards.
How to read the label so timing works for you
Harvest date is most important. It says when the olives were picked and pressed. Aim to choose the most recent available harvest date.
The "best before" date can mislead. It is set from the bottling date, not the harvest, and oil can sit in tanks for a long time before it is bottled. In the EU, best-before dates are capped at 18 months from bottling and 24 months for oil exported outside the EU. In some countries where domestic olive oil is not as regulated, various year dates may appear.
The crop year is a long time span. A label reading "2025/26" gives the season, not the month, and a harvest can span five months, so this format can hide a four-month freshness gap. A precise harvest date is far more useful.
Storage protects the oil from breaking down. Even fresh oil degrades fast in light and heat. Oil should be purchased in a dark glass or tin and stored sealed in a cool place.
